  • the transfer process takes place not only from hand to hand, for example when shaking hands, but also indirectly via surfaces that are touched by many hands.
  • the transmission process is promoted by the fact that doorknobs and door openers are used by many hands one after the other, whereby the germs are passed on through contact with the contact surface of the door handle.
  • DE 19857268 A1 describes surfaces of objects, such as door handles, which are equipped with fluid guides and can be acted upon by a fluid reservoir with a correspondingly disinfecting liquid.
  • an antibacterially coated fitting for example a door handle, is given a PVD coating made of copper or with a copper component that has an antibacterial effect.
  • handles or surfaces that are touched by people are known which are provided with a coating or a cover which is designed to be antibacterial or disinfectant.
  • US 2005/0267233 A1 shows a cross section of a handle bar that is covered once with an antibacterial material or an antibacterial layer.
  • EP 3473096 A1 describes a body contact element with an antibacterial and antimicrobial effect.
  • Door handles are also described as a body contact element.
  • the cover or the coating can be designed as a plastic injection-molded component, a plastic extrusion component, a plastic thermoforming component, a plastic blow-molded part or a 3-D pressure component.
  • the coating consists of plastic material mixed with the active ingredient.
  • DE 102009053663 B3 also relates to a handle assembly that consists of sleeve segments that can be mounted around a door handle, for example, and that consist of an absorbent carrier material in order to receive an antibacterial disinfectant.
  • EP 2 098664 A1 Prior art according to the preamble is known from EP 2 098664 A1.
  • the document shows a handle cover for door handles, which consists of a tubular cover with an open and a closed hose end and is made up of an elastic material with an antibacterial effect.
  • the cover should be formed from a fabric into which silver threads, in particular, are woven.
  • the permanent fixation of a cover to such handles has proven to be problematic. Even with elastically expandable tubular covers, wandering, slipping and finally falling of the cover from the door handle cannot be permanently avoided, even when used solely as intended.
  • fastening elements are therefore provided between the door handle and the cover, which are designed as Velcro elements, for example.
  • the object of the invention is therefore to design a handle with an antiseptic cover in such a way that the cover is securely and firmly fixed on the handle for a period of use.
  • the cover is a shrink tube that is shrunk onto the handle means that the cover is pressed over the entire surface of the handle surface, so that permanent, non-slip adhesion to the handle is achieved through contact friction alone. It is not possible to remove the cover simply by using the handle as intended or by consciously pulling it.
  • the disinfecting active ingredients have a bactericidal, sporicidal, fungicidal and / or virucidal effect
  • the disinfection can be provided with a suitable active ingredient for the respective hazard potential with which the relevant handle is to be assessed.
  • the shrink tube has a shrinkage ratio of 2: 1 to 6: 1 when heated, a secure attachment of the cover is achieved even with handles with a cross-section that varies greatly over the handle length, since it is nevertheless completely in contact. It has been shown that the 90 ° bend that is always present in door handles at the attachment point on the door for typical L-shaped door handles, as well as a further 90 ° bend, such as for U-shaped door handles, do not pose a problem for shrinking the cover.
  • the elastic material of the shrink tube contracts when heated so that the grip surface of the handle is always completely enclosed.
  • the shrink tube can also be pushed over the above-described 90 ° bend (s) as well as any decorations, so that after the shrinking on, a handle essentially completely enclosed by the cover is formed.
  • the full-surface contact of the shrunk-on cover in addition to the mechanically tight fit, also ensures that neither pathogens nor dirt can penetrate between the cover and the handle.
  • tubular cover is designed to be closed on one side, the free end of the handle is also completely enclosed, so that the desired disinfecting effect of the cover is also developed there. Contact infection by touching a free end that is not enclosed can thus be ruled out.
  • Suitable adhesives are, for example, thermoplastic plastic adhesives, which are also activated by the heat when the shrink tube is heated to shrink it onto the handle.
  • the elastic material of the shrink tube is made of thermoplastic material.
  • the corresponding disinfecting agents are bound or embedded in this material.
